8. Model Name: Greenhouse Effect Model
Working Principle: The model illustrates the greenhouse effect by
trapping heat inside a transparent container with carbon dioxide.
Materials Required: Glass jar, thermometer, water, vinegar, baking soda,
and a balloon.
DIY Making Procedure:
a. Fill the glass jar with water and add vinegar.
b. In a separate balloon, add baking soda.
c. Stretch the balloon over the jar's mouth, ensuring it's airtight.
d. Tilt the jar to mix the baking soda with vinegar, producing carbon
dioxide gas.
e. Place the jar in direct sunlight and observe the temperature rise inside
the jar due to the greenhouse effect.
Why Is The Model Useful: This model helps students understand the
greenhouse effect and its role in regulating Earth's temperature.
Tips for Presentation: Explain the consequences of the enhanced
greenhouse effect and its impact on climate change.
